Lara Stone x Calvin Klein Underwear

She stars in the new 'Push Positive' campaign.

Lara Stone (who we were just lurking on Instagram yesterday) stars in Calvin Klein Underwear's 'Push Positive' campaign. Not that her chest — or any part of her physical being — needs enhancement. The gap-toothed beauty is no rookie when it comes to stripping off — she got very naked for this year's Pirelli Calendar alongside fellow supermodels Kate Moss and Rinko Kikuchi.

The digitally-focused campaign was shot in New York by Steven Klein, who just did Lady Gaga's vastly different Fame fragrance trailer, and includes a video of Lara (in undies, obviously) to be released on YouTube in the first week of September.
